Your doing nothing but wasting your money when u could use the dilution method. Listen to FBR:

"Detox drinks will contain will contain fiber and salts such as potassium and sodium. Those salts will raise your specific gravity slightly and fiber can help slightly. But you can get potassium and sodium from sports drinks for a mere fraction of the cost as well as a bottle of Metamucil for a mere fraction of the cost of a detox kit".

As well as vitamins you will also need to get your creatine levels up. Detox drinks will also claim to have creatine, but taking it 3-5 hours before the test is useless. FBR:

"Taking a product with creatine shortly before a test is useless. They do not measure creatine, they measure creatinine and it takes your body 48-72 hours to metabolize creatine to creatinine. So you see taking a product with a creatine 5 hours before the test will not raise creatinine clearance".

All of this being said... If you feel more comfortable wasting your money thats your choice. I would follow the dilution method and spend that extra money on weed.:jointsmile:
